NVIDIA Launches The GTX 980 For Notebooks.

NVIDIA HAS ANNOUNCED its latest notebook mobile gaming GPU, the GeForce GTX 980, which it claims is the first of its kind to match the performance and features of a desktop gaming GPU.The GTX 980, and all of its 2048 cores, will be available in early October as laptops from MSI, Gigabyte, Asus, Clevo, and Aorus should be available for purchase.What this means in practice is while the 980M achieved around 70 to 80 per cent of its full-fat sibling, the laptops equipped with the GTX 980 will be able to harness the whole of the card’s hardware for gaming, video editing and so on. That’s helped by the full 2048 CUDA core architecture of the component, unchanged from its desktop PC counterpart, as well as the overclockable nature of the card – an overclocking tool will accompany the new laptops.

Play the latest games — such as The Witcher III: Wild Hunt, Grand Theft Auto V, Mad Max, Metal Gear Solid: The Phantom Pain and The Killing Floor 2 — at maxed out graphics settings. For example, VR requires 5 million pixels at 90 frames per second (450 MP/s) compared to PC gaming that only needs 2 million pixels at 60fps (120 MP/s). Alongside this, there will be five other GTX 980-powered notebooks when it launches, including a MSI GT72 and GT80, a Clevo P870DM and P775DM, and an Aurus X7 DT. Nvidia said that this chip will revolutionise notebook gaming as gaming won’t be about making a choice between performance, premium components or overclocking between notebook and desktops, as “they are now on par; it’s a choice of form factor”. µ You might think this approach means it’s a limited-edition vapor part that vanishes once the cream of the crop is exhausted, but Nvidia said it’s not.

For the utmost in performance, graphics cards use very wide parallel memory buses, which means cramming identical-length wires into a tiny amount of space. This can lead lead to interference that can kill performance, but Sanghani said the new card can hit the same exact same memory bandwidth of the desktop card.

When asked if the use of HBM memory would have been easier, Nvidia officials said this new GTX 980 hit the RAM speeds it needed to with what it has, and oh yeah, unlike HBM, you can actually get the GDDR5 used in the new GPU. AMD and its RAM partner SK Hynix have never commented on the yields of the new HBM memory, but there’s growing suspicion in the industry that the hard-to-get next-generation RAM could be holding back wider availability of AMD’s new Fury lineup.

If you think of a phase as an individual channel, adding more phases generally means each channel has to work less, which in theory increases reliability and stability. Overclocking implementation can be decided by the notebook builder and will be dependent on the capabilities of the platform, but one demonstration showed the card running with about a 200MHz boost overclock. Here’s the screenshot I snagged of the score from the desktop PC here after it finished: Of course, we’ll withhold judgement until we actually see a machine in our hands but it’s highly unlikely the company is making this up to fall flat on its nose. Before you go off one-third cocked about the CPUs being different among the tested systems, keep in mind that again, this is not the final verdict, this is just the results of the demo to whet your appetite.
